CoinFello, an AI agent optimized for interacting directly with any EVM smart contract, today announced the release of its open source OpenClaw skill in partnership with MetaMask. The new integration enables Moltbots, personal AI agents running on OpenClaw, to securely execute onchain transactions using delegated smart wallet permissions.The launch introduces a new framework for connecting AI agents with crypto wallets while maintaining user custody of private keys. By leveraging ERC-4337 smart accounts and ERC-7710 delegations through the MetaMask Smart Accounts Kit, the CoinFello OpenClaw skill allows Moltbots to grant other agents, such as CoinFello, narrowly defined delegations to act on their behalf. This represents a significant advancement in agentic wallet security compared to the current status quo, where agents typically store private keys or API credentials in plain text.The system follows the principle of least privilege. A user’s Moltbot can grant CoinFello, and eventually other compatible agents, only the permissions required to complete a specific task, ensuring no agent receives broader wallet access than necessary. When a user submits a natural-language request, CoinFello converts the instruction into a delegated transaction and validates it in an evaluation layer before execution. "If we want agents to participate meaningfully in the onchain economy, we need a security model that is better than handing an autonomous system a private key," said Brett Cleary, CTO at CoinFello. "The CoinFello Skill introduces hardware-isolated keys and fine-grained delegations, giving AI agents a secure way to execute transactions while helping bootstrap onchain capabilities for the broader agent ecosystem."The release comes amid the rapid growth of the OpenClaw ecosystem. Over the past two months, the OpenClaw GitHub repository has surpassed 150,000 stars and 22,000 forks, while npm downloads exceeded 416,000 in the previous 30 days. Until now, many AI agent wallets have given the agent direct access to a private key or API credential, exposing sensitive secrets within the agent’s runtime and creating a large attack surface.Some newer designs attempt to mitigate this risk by using server-side trusted execution environments (TEEs), but they still rely on centralized infrastructure.The CoinFello skill takes a different approach. The signing key stays on the user’s device, while tasks are carried out through fine-grained ERC-7710 delegations. Agents can execute actions without ever accessing the private key.Using the CoinFello skill, Moltbots can perform a wide range of blockchain actions via natural-language prompts. Supported capabilities include swapping between ERC-20 assets, bridging across EVM networks, interacting with NFTs such as ERC-721 or ERC-1155 tokens, staking, lending, automatic rebalancing of token portfolios, and executing multi-step trading strategies.The CoinFello OpenClaw skill is built on the Agent Skills specification and is compatible with OpenClaw environments and Claude Code. The implementation is released under the MIT license, allowing developers to freely deploy, modify, and contribute to the skill in their own AI agent environments.CoinFello notes that the system is designed to remain open and configurable. While CoinFello acts as the default Web3 agent, Moltbots can delegate permissions to any compatible onchain agent. The company says future development will focus on expanding permissions frameworks and deeper integrations with the MetaMask Smart Accounts Kit to support broader portfolio management features.Interest in the intersection of AI agents and crypto infrastructure has accelerated in recent months as developers experiment with autonomous software agents capable of interacting with decentralized networks. The CoinFello OpenClaw skill aims to provide a secure foundation for this emerging category by bridging natural language interfaces with onchain execution.About CoinFelloCoinFello is an AI agent designed to explain, execute, and automate interactions with smart contracts. Built for self-custody, the platform is currently available in private alpha for end users, with developer versions expected soon. CoinFello supports EVM-compatible networks, leverages EigenAI to enable a self-custodied AI environment, and integrates the MetaMask Smart Accounts Kit to give users control over their assets.
